1. The problem statement, all variables and given/known data The Matricial Circuit of a certain circuit in time-domain is: [ -1 D+a] [v1(t)] = [es(s)] [D+2 -1] [v2(t)] [0 ] where a is constant >0. Find G1(s) = V1(s)/Es(s). Put your result in a relation of polinomials N(s)/D(s), with the D(s) monic polinomial 2. Relevant equations 3. The attempt at a solution So, i tried to Laplace transform the matrix and then resolve the matrix equation, find V1(s) and then put V1(s)/Es(s). But D(s) is not a polinomial in this case. Am I missing something? I think that there is a way to obtain D(s) but I'm not finding it. The book that I am using to study is Fundamental of Electrical Circuits 5th edition by Sadiku. Thanks, guys!
